a00b10c360 drm/i915: Only enforce fence limits inside the GTT.
So long as we adhere to the fence registers rules for alignment and no
overlaps (including with unfenced accesses to linear memory) and account
for the tiled access in our size allocation, we do not have to allocate
the full fenced region for the object. This allows us to fight the bloat
tiling imposed on pre-i965 chipsets and frees up RAM for real use. [Inside
the GTT we still suffer the additional alignment constraints, so it doesn't
magic allow us to render larger scenes without stalls -- we need the
expanded GTT and fence pipelining to overcome those...]

e5281ccd2e drm/i915: Eliminate nested get/put pages
By using read_cache_page() for individual pages during pwrite/pread we
can eliminate an unnecessary large allocation (and immediate free) of

Play safe and use the common routines which take care of the cachability

Whilst they should be cacheable for the current generations, actually

fb7d516af1 drm/i915: add accounting for mappable objects in gtt v2
More precisely: For those that _need_ to be mappable. Also add two
BUG_ONs in fault and pin to check the consistency of the mappable
flag.

Changes in v2:
- Add tracking of gtt mappable space (to notice mappable/unmappable
  balancing issues).
- Improve the mappable working set tracking by tracking fault and pin
  separately.

201728429d intel-gtt: maximize ggtt size on platforms that support this
On VT-d supporting platforms the GGTT is allocated in a stolen mem
section separate from graphcis stolen mem. The GMCH register contains
a bitfield specifying the size of that region. Docs suggest that this
region can only be used for GGTT and PPGTT. Hence ensure that the
PPGTT is disabled and use the complete area for the GGTT.

Unfortunately the graphics core on G33/Pineview can't cope with really
large GTTs and the BIOS usually enables the maximum of 512MB. So
don't bother with maximizing the GTT on these platforms.

b3eafc5af0 intel-gtt: save PGETBL_CTL later in the setup process
... and switch to a more classical store-reg-on-suspend, restore-on-resume
way of doing things. Obviously this is just preparation for the future,
the code is not there at all, yet.

This is needed because the next patch adjusts this register and everything
in it (not just the pagetable address) needs to be restored on resume.

Fix up trivial conflict in arch/x86/xen/mmu.c, and fix the use of

'memblock_x86_reserve_range()' instead. Pointed out by Jeremy.

135cba0dc3 vmwgfx: Implement a proper GMR eviction mechanism
Use Ben's new range manager hooks to implement a manager for
GMRs that manages ids rather than ranges.
This means we can use the standard TTM code for binding, unbinding and
eviction.

5f2365d8c2 misc devices: do not enable by default
Do not enable this Kconfig menu by default since it contains devices not
present on the majority of systems.

This is becoming a pain and a waste of time especially when doing a bunch
of kernel builds on different systems daily and have to answer "make
oldconfig" prompts for strange devices.
